Meanwhile with the idea of protecting the environment and reducing the rubbish we also repurchase the used or scrap tri-cone rock bits, PDC drill bits or replace the old with new ones.

PDC Drill Bits

The main structure features:

1. Tungsten carbidematrix PDC possesses high wear resistance and impact resistance.
2. Parabolic crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life.
3. Applying hydraulics balance design, 5 renewal nozzles and reasonable nozzles locating angle can gain ideal fluid field in well bottom, fully clean and cool cutter, and prolong the cutter working life.
4. Non-symmetry blade arrangement enhances drilling well balance.
5. Optimization for cutter shape, slant angle, cutter numbers prolong the cutter working life in combination with high quality PDC cutter, and improve ROP and drilling efficiency.
6. It can be used on rotary or down hole motor.
7. High HIS is recommended.

Rock Bits OperationGguide

Attention should be paid to the following iterms in order to get better resoult:

1. Inspect on the bit's size and type before the bit running into the well like to check if the size is right as well as the type of pin shank of rock bit is fit for that of the joint or the jet nozzles is set properly.

2. Check the well bottom and clean up all the fallen stuff.

3. Bit can be applied in the well only after its joint with driller and balance must be kept with a speed under control.

4. Bits shall be especially prevented from hitting the wall of well in irregular drilling sections and by this way the break of teeth or bits shirttail, which may lead advance failure of the sealing, can be avoided.

5. The pump shall be started to cycle the mud when the new drilling bit is 3 to 5 meters away from the well bottom. Do not start the conveying disc after the pressure has been applied on bits.

6. When touching the well bottom, the bits shall be slowly and slightly rotated for 30 minutes to make a new bottom and then be applied with pressures with normal targets.

7. During the drilling, balance must be kept and bit shall be applied evenly without stop.

8. The bits shall be kept dry, ventilated, out of exposure of sunshine, raining and high temperature during the transportation and storage.

9. All bits are not fit for wiping, especially with high rotation speed.

10. Low rotation speed shall be selected when high drilling pressure is applied. Maximum values of drilling pressure and rotation speed at the same moment is prohibited.

11. Cleaning job shall be done in the bottom of well before further drilling when there is dirty or with fallen stuff.

12. The rotation speed of bits shall be controlled in recommended scope. Pressure in well shall be applied evenly without break.

13. Operator shall concentrate his energy when doing drilling job and guard against the sliding of bits. Also operator shall analyze and carry out further methods when finding abnormal appearances like jumping of bits.

14. It is normal that the tooth wheel is hard to be manually rotated when new bits with sealing roll bearing are applied. Do not immerse the bits in oil or knock the bits with heavy object.

QUALITY GUARANTEE

According to the product quality law of the People’s Republic of China, in order to protect the legitimate interest both the user and manufacturer, here we would like to make the promise as follow:

1.      Producing abiding with API Q1 & Spec7 standard and the Chinese standard of SY/T5164, SY/T5217 and Q/JZ.J.2.

2.      Since the date of sale, in the warranty period there should be not the material fault and the producing defects of impacting on the usage.

3.      If the client can present the real and related documents to prove the product don’t meet the quality standard, we would like to make the replacement or refund.

4.      The Service period: the 90 days after sales.

As the company can not control the products in market and in drilling operation, and can not predict the complexity of the underground work environment and the variability of the drilling operations, thus can not ensure that the drill bits sold to meet any specific outcome or competence for a particular purpose, does not guarantee the comparability of the drill bit drill in the proper use under the conditions of normal use. Therefore, we will not bear any responsibility for the result of product defects and loss of the following acts:

1.      The damage to the drill bit and its parts because of the improper handling and storage; the failure beyond the warrantee of rubber, oil, materials aging, etc.

2.      The rebuild bits;

3.      The damage duo to improper operation

4.      Changing the construction with special purposes or using the nonstandard components.

5.      Using the improper nuzzles and wrong installation.

The guarantee applies to the first clients who receive the products which are sold by ourselves and our agency.
